So I'm about 8 hours into my firust carb rebuild ever, should've started with a lawn mower. I've got all the jets and bleeds out of the main body. Everything is accounted for as far as the diagrams I've got and I flip the main body over and a brass tube measuring 14x4mm falls out. I have no idea where it came from nor where it's going. If anyone has an answer it would be appreciated. I'll be posting this on OhioRotaries and SMW also.
